About the guides

The guides on this site are published by DLEM. This page says how they are written, who checks them, where the numbers come from and how to tell us about a mistake.

Who publishes them

The guides are published by DLEM. There is no individual author: the byline is the publisher. The app’s independent developer, the data controller named on the Privacy page, reads and approves them and is responsible for what is published.

How they are written

Drafts are written with the help of AI tools. Nothing is published until a person has read it and approved it. An article is first written in English and then adapted for each market, with its own currency, units, taxes and sources, rather than translated word for word.

A person reads the English version and the Brazilian Portuguese version of every article in full. The other versions are checked by automated tools and compared with the English before they are published.

Where the numbers come from

A figure in a guide is one of two things: the article’s own arithmetic, with the formula shown and example values that are only examples, or a number from an official source, linked at the end of the article. We do not publish invented statistics, quotes or personal stories.

What the guides are not

The guides are general information for drivers. They are not tax, legal, insurance or financial advice. Rules and prices differ by country and change over time, so check your own case with the authority or a professional.

Companies and DLEM

The guides do not name ride-hailing companies. A guide may end with one sentence about DLEM, the app we are building, and a link to the waitlist. The guides are meant to be useful without it.
